drivers/spi: Add flash probe callbacks to spi_ctrlr structure

In order to support some specialized SPI controllers that are actually
SPI flash controllers, define a new spi_flash_ctrlr structure with the
following members:

1. probe: Specialized probe function provided by the spi flash
controller.
2. try_generic_probe_first: Check if the controller wants the flash
driver to perform generic probing before trying out the specialized
probing.

With this change, the specialized spi flash probe functions are now
associated with a particular spi ctrlr structure and no longer
disconnected from the spi controller.

BUG=b:38330715
TEST=Verified with the entire patch series that spi flash driver still
works fine on poppy.
